A Study on the Metallic Surface Roughness Measurement by Laser Diode Beam

반도체 레이저 비임을 이용한 금속표면의 거칠기 측정에 관한 연구

A new technique for the measurement of surface roughness based on the Intensity fluctuations of laser light backscattered form a moving surface has been introduced. The developed method will be quite useful for evaluating the surface quality under machining with more detailed Information by detecting the surface roughness along both directions simultaneously.
